An analysis of the peculiar features of optical wire antennas with displaced terminals is presented. Full-wave simulations and a semi-analytical technique based on Pocklington’s equation are used in order to systematically study the behavior of input impedance and field enhancement at the antenna terminals when the feed-gap region is shifted with respect to the center of the wire. A simple analytical model based on the evaluation of the effective wavelength of the propagating surface wave is also suggested for the interpretation of the results.
